I inherited a Citrix 4.5.8 nightmare. The citrix farm had not undergone any maintenance for a significant period of time.

I've since started updating the server but when trying to install OSE450wk23X64R07 the server configured for something akin to about 18 hours. After stopping the process and rebooting all service appear to start and run as expected, but when trying to discover the Farm from the Access Management Console I get the following error: "Errors occurred when using 'Servername' in the discovery process." The details show:

"Citrix MFCOM Service did not respond as expected. Make sure that your user account is a member of this computer's Distributed COM Users group if you are connecting to a remote server. Check the version of Citrix Presentation Server on the computer and make sure that a compatible version of Citrix MFCOM Service is installed and running."

The server is Windows 2k3 x64 SP2.

Is it possible that the Citrix Roll up package damaged the MFCOM service connection in some way?
